- A while back I picked up a no-warranties 3b1 expansion box. I
- finally got around to setting it up, and sure enough, it doesn't
- work. The 3b1 gets a fine hatching on the screen with the box
- attached, and fails to boot. When the box is attached but
- powered down, there is no hatching, but the the machine hangs
- while loading the boot disk. (The usual sequence is box on
- before 3b1, but I thought I'd try booting with the box attached
- but powered down.)
-
- It looks like the expansion box is NOS, i.e., has never beed
- used, or maybe was powered up once and carefully repackaged.
- Supply voltages are ok, and simple things like reseating
- connectors did not help.
-
- I know this is a long shot, but has this happened to anybody
- before? Assuming the box worked when it left the factory, the
- connector seems a likely culprit, but without a spare box to
- swap parts with (or a pair of spare 50 pin cables) there's no
- easy way to check things.
